BCN三元化合物的合成研究

Research of BCN Ternary Compound Preparation

新材料是科技进步的物质基础,其他学科的发展都依赖于材料科学的进步与发展.随着科学技术的迅速发展,人们对各种材料的性能有了更多的认识.硬度是材料最重要、最基本的性能指标之一,具有超硬性质的功能材料的合成及其性质的研究是目前凝聚态物理和材料科学领域研究的热点之一.近年来,基于硼碳氮体系结构和功能材料的理论设计和新相的发现,引起了人们在理论和实验上对硬度接近甚至超过金刚石的新型材料的研究兴趣.本文就BCN三元化合物超硬材料的研究进展做一综述.

New materials are the matter basis of scientific and technological progress and the precursor of the contemporary socio-economic. Any other subjects will rely on the progress and development of materials science. Along with the rapid development of science and technology, people have had more understanding to the function of a variety of materials and approach to the processing of materials. As hardness is one of the most important and fundamental properties of materials, the synthesis, characterization and properties of materials with super hardness become one of the highlights in condensed matter physics and materials science and technology at present.The recent progresses in materials design, as well as the discoveries of new phases, in the B-C-N system, has aroused great interest among scientists to seek mate-rials with hardness comparable to or even higher than diamond, both experimentally and theoretically.
